My suggestion to you if you are at the point of frustration is to contact and attorney and keep him on stand by for the next conversation you will have with Harley. Do not threaten them with a lawyer so to speak, let them know you have contacted one and you are ready to move forward legally if the following demands arent met.
The demands being what you stated above that are bothing you. IE new engine or cases, all items chipped or peeling replaced and new heated hand grips. If not be prepared to fight them it is chasing good with bad, but you get to a point of utter frustration and for a 35k motorcycle one should not have to put up with this
The customer service manager is Rusty Dire, but the person you probably want to be put in contact with is the public relations person. You may have an out of service warranty as well depending on state and number of days your bike has been in for repair for each item. In florida it is 30 days.
I would fight them you have nothing to lose except a lot of hair, and time sink.
